NEi Explicit 2010 Introduced for Nastran, FEM Analysis
 WESTMINSTER, CA,
Nov 3,
2009 - NEi Software, a global provider of NEi Nastran Finite Element
Analysis (FEA) software, announced the addition of an explicit dynamics
program to their simulation software suite - NEi Explicit 2010. This code
has been used commercially since 2006, but has been enhanced by the lead
developer, Dr. Lee Taylor, specifically to meet the needs of NEi's customers
in the aerospace, automotive and maritime industries.

armor plating uses a nonlinear material with element deletion to
accurately simulate the energy absorption capabilities of the plate

NEi Explicit solves nonlinear impact problems that involve large
deformations with complex contact and motion. Typical applications include
crash, metal forming processes, drop tests, and ballistic scenarios. NEi
Explicit can also be used to solve static problems with millions of degrees
of freedom. Because they are extremely large and highly contact dominated,
these problems are difficult to solve using implicit FEA codes.
Several examples of NEi Explicit applications along with product
information can be found at
www.NEiExplicit.com. The animated solutions in the examples include a
bird strike on a turbine engine, a bullet impacting armor, a sheet metal
stamping operation, and fracture of a plastic buckle.
Key Features of NEi Explicit
- Complete integration with the NEi Nastran environment
- Automatic contact generation
- Rigid materials definition
- Material deletion criteria with element deletion and automatic
reconstruction of contact surface due to surface erosion
- Parallel performance
- Compelling price point
To help launch NEi Explicit, NEi Software will host an instructional
webinar titled "When Nastran Goes Explicit" on Wednesday, November 4th at
11:00 AM - 12:00 PM PST. The webinar will explain the differences between
implicit and explicit FEA and demonstrate the use of explicit FEA through
examples and applications using NEi Explicit. Sign up for the webinar is at
www.NEiSoftware.com/webinar/explicit.
